I can't figure out the operator overloading...

Question

Can any body explain the operator overloading and give me the answer of queue management 2

Answer 1

the main idea behind “Operator overloading” is to use C++ operators with class variables or class objects. Example:

class Complex {
private:
int real, imag;

public:
Complex(int r = 0, int i = 0)
{
real = r;
imag = i;
}

// This is automatically called when '+' is used with
// between two Complex objects
Complex operator+(Complex const& obj)
{
Complex res;
res.real = real + obj.real;
res.imag = imag + obj.imag;
return res;
}
void print() { cout << real << " + i" << imag << '\n'; }
};

int main()
{
Complex c1(10, 5), c2(2, 4);
Complex c3 = c1 + c2;
c3.print();
}
